description Publicationkeyboard_double_arrow_right Article 2016 SpainPublisher:Asociación Española de Historia Económica (AEHE) Authors: Rubio Varas, María del Mar; Torre Campo, Joseba de la;Rubio Varas, María del Mar; Torre Campo, Joseba de la;En 1972, Henry Kearns, presidente y director del Export-Import Bank de los Estados Unidos (Eximbank), visitó la Cámara Oficial de Comercio e Industria de Madrid. El título de su discurso'España – el cliente del billón de dólares del Eximbank' daba cuenta del importante papel que el banco público estadounidense jugaba en la financiación de las compras españolas de bienes de equipo, como aviones, fábricas de acero, estaciones satelitales y plantas eléctricas, entre otros. La concentración en nuevas instalaciones de generación eléctrica convertía a España en aquel momento en el país con el más rápido desarrollo de energía nuclear de Europa, y el mayor comprador de tecnología nuclear de los EE.UU. mano a mano con Japón. Ninguna otra nación se acercó a estos dos en ese sentido. Utilizando materiales de archivo del Eximbank y la Administración Nacional de Archivos y Registro de los Estados Unidos (NARA), exploramos las facilidades financieras que los EE.UU. proporcionaron al programa nuclear español, el tamaño de los créditos autorizados y su evolución en el tiempo. Se hace evidente que el bombeo de dinero público norteamericano para la exportación de las instalaciones nucleares en el mundo explica en gran medida el cuasimonopolio del mercado nuclear mundial que los EE.UU. tuvieron antes de la década de 1980, y en particular su importancia para convertir a España en uno de los pioneros y líder en la adopción de la tecnología nuclear. In 1972, Henry Kearns, President and Chairman, Export-Import Bank of the United States (Eximbank) visited the Official Chamber of Commerce and Industry in Madrid. The title of his speech 'Spain—Eximbank’s Billion Dollar Client' gave notice of the important role that the public American bank had for financing the Spanish purchases of capital equipment: aircrafts, steel mills, satellite grown stations, power plants, etc. The heavy concentration on new power facilities at the time made Spain the fastest growing nuclear power developer in Europe, and the largest nuclear power buyer from the US with Eximbank’s support head-to-head with Japan. No other nation approached these two in that respect. Investigating archival materials from the Eximbank and the National Archives and Record Administration of the United States (NARA), we explore the financial facilities the US provided to the Spanish nuclear program, the size of the authorised credits and its evolution over time. It became apparent that the role of the US in pumping public money for exporting nuclear facilities to the world explain a great deal of the US quasi-monopoly of global nuclear market before the 1980s, and in particular for turning Spain into an early adopter and champion adopter of nuclear technology. Financial support from the Bank of Spain (grant agreement 30/6/2012) and the Spanish Ministry of Economics and Competitiveness (project ref.: HAR2014-53825-R) is dully acknowledged.

Spain was the first developing country to exploit a nuclear power plant commercially. By the early 1970s Spain had become the major nuclear client of the USA, the world’s largest reactor exporter. Despite its importance, historians are just beginning to revisit and establish the sequence of the events that make up Spain’s nuclear history. This article analyses the role played by the state in enabling one of Western Europe’s poorest countries to join the exclusive nuclear power club. In a departure from the technological approach used in previous literature, the history of Spain’s progress in the nuclear power field is retraced against the background of its political and economic evolution.

Pese a su relevancia, la historiografía económica de la energía nuclear está tan sólo en sus inicios. Este trabajo analiza el papel que el Estado jugó para conseguir que uno de los países más pobres de Europa occidental entrara en el exclusivo club de países productores de esa energía. Proponemos una nueva periodización del avance de la energía nuclear en España basada en la evolución político‐económica del sector que va más allá de los estadios tecnológicos que se describen en la literatura. Three decades after the governmental decision of paralysing and reshaping the Spanish atomic program designed over the developmentalism years, the controversy remains open. Despite its relevance, the economic historiography of nuclear energy is on its infancy. This paper analyses the role that the state played for making possible that one of the poorest countries in Western Europe entered the exclusive club of nuclear producing countries. We offer a new periodization of the development of nuclear energy in Spain based on the political and economic evolution that goes beyond the technological stages described in the existing literature.

Se trata de un ejemplo de industria naciente que, bajo la protección del Estado y la acción de los consorcios empresariales y de las multinacionales norteamericanas, fue capaz de replicar un reto tecnológico complejo. Analizamos cómo se fue creando un ecosistema empresarial en el que fue clave el liderazgo de algunos ingenieros y la cooperación y competencia entre industrias, ingenierías y consultoras. La historia empresarial de las centrales nucleares de Zorita y Garoña ejemplifica un modelo de learning by doing que, a través de los contratos 'llave en mano', permitieron un rápido crecimiento del sector, convenciendo al gobierno de la dictadura y a los promotores eléctricos de que era posible llevar a cabo uno de los programas nucleares más ambiciosos de la Europa occidental. This article explores the learning and technology transfer processes that placed Spain among the firstcomers of nuclear energy in the late 1960s. It is an example of a infantindustry that, under the protection of the State and the action of the business consortiums and of the North American multinationals, was able to replicate a complex technological challenge. We analyzed how an entrepreneurial ecosystem was created in which the leadership of some engineers and the cooperation and competition between industries, engineering and consultants were key. The business history of the Zorita and Garoña nuclear power plants exemplifies a model of learning by doing that, through turnkey contracts, allowed a rapid growth of the sector, convincing the dictatorship government and the electric promoters that it was possible to carry out one of the most ambitious nuclear programs in Western Europe.

Power-to-methane (PtM) systems may allow fluctuations in the renewable energy supply to be smoothed out by storing surplus energy in the form of methane. These systems work by combining the hydrogen produced by electrolysis with carbon dioxide from different sources to produce methane via the Sabatier reaction. The present work studies PtM systems based on the CO supplied by the chemical looping combustion (CLC) of biomass (PtM-bioCLC). Life- cycle- assessment (LCA) was performed on PtM-bioCLC systems to evaluate their environmental impact with respect to a specific reference case. The proposed configurations have the potential to reduce the value of the global warming potential (GWP) climate change indicator to the lowest values reported in the literature to date. Moreover, the possibility of effectively removing CO from the atmosphere through the concept of CO negative emissions was also assessed. In addition to GWP, as many as 16 LCA indicators were also evaluated and their values for the studied PtM-bioCLC systems were found to be similar to those of the reference case considered or even significantly lower in such categories as resource use-depletion, ozone depletion, human health, acidification potential and eutrophication. The results obtained highlight the potential of these newly proposed PtM schemes.

Previous papers on this topic fall short as comparing finite-element models with simplified versions of resistance–capacitance models. It was confirmed that resistance–capacitance models replicate results of finite-element models in the simulation of a thermoelectric module under steady-state conditions. Deviations lower than 3 % in electric power and efficiency (ratio of electric power to heat input) are obtained for temperature differences between heat source and heat sink as large as 200 K. Similarly, deviations lower than 3 % are obtained for simulation of a thermoelectric module under transientstate conditions. Resistance-capacitance models not only replicate values, trends and rates of variation predicted by finite-element models under step, linear and sinewave variations in the boundary conditions, but they also do this with negligible computational cost.

An important issue in thermoelectric generators is the thermal design of the heat exchangers since it can improve their performance by increasing the heat absorbed or dissipated by the thermoelectric modules. Due to its several advantages, compared to conventional dissipation systems, a thermosyphon heat exchanger with phase change is proposed to be placed on the cold side of thermoelectric generators. Some of these advantages are: high heat-transfer rates; absence of moving parts and lack of auxiliary con- sumption (because fans or pumps are not required); and the fact that these systems are wickless. A com- putational model is developed to design and predict the behaviour of this heat exchangers. Furthermore, a prototype has been built and tested in order to demonstrate its performance and validate the compu- tational model. The model predicts the thermal resistance of the heat exchanger with a relative error in the interval [?8.09;7.83] in the 95% of the cases. Finally, the use of thermosyphons with phase change in thermoelectric generators has been studied in a waste-heat recovery application, stating that including them on the cold side of the generators improves the net thermoelectric production by 36% compared to that obtained with finned dissipators under forced convection. The authors are indebted to the Ministry of Economy, Industry and Competitiveness-Government of Spain and FEDER Funds for economic support of this work, included in the DPI2014-53158-R Research Project.

Waste heat generation has a widespread presence into daily applications, however, due to the low-temperature grade which presents, its exploitation with the most common technologies is complicated. Thermoelectricity presents the possibility of harvesting any temperature grade heat; besides it also includes many other advantages which make thermoelectric generators perfect for generating electric power from waste heat. A prototype divided into two levels along the chimney which uses the waste heat of a combustion has been built. The experimentation has been used to determine the parameters that influence the generation and to validate a generic computational model able to predict the thermoelectric generation of any application, but specially applications where waste heat is harvested. The temperature and mass flow of the flue gases and the load resistance determine the generation, and consequently, these parameters have been included into the model, among many others. This computational model incorporates all the elements included into the generators (heat exchangers, ceramics, unions) and all the thermoelectric phenomena and moreover, it takes into account the temperature loss of the flue gases while circulating along the thermoelectric generator. The built prototype presents a 65 % reduction in the generation of the two levels of the thermoelectric generator due to the temperature loss of the flue gases. The general computational model predicts the thermoelectric generation with an accuracy of the ±12 %. The authors are indebted to the Spanish Ministry of Economy and Competitiveness for the economic support to this work, included in the DPI2014-53158-R research project.

Nuclear energy was one among business opportunities brought by the take off in science and technology after the Second World War. The narratives of the milestones of atomic history neglect the commercial, industrial and organizational aspects that made it possible. This paper concentrates on what makes the nuclear business exceptional (or not). We undertake an analysis of the nuclear supply business (designing, manufacturing and installing nuclear facilities) distinct from the analysis of the demand side (business operating nuclear power plants). We identify a continuing role of the state in civil nuclear businesses and a symbiotic relationship with private atomic business. And yet, for the most part the nuclear business applies the usual criteria of cost minimization and profit maximization within the boundaries of a non-perfectly competitive market. We argue that the development of civil nuclear projects is core not just to business history as a discipline but to post-war history. © 2021 The Author(s).

Aranguren; Miguel Araiz; Gurutze Perez; David Astrain;Despite being one of the largest renewable sources, geothermal energy is not widely utilized for electricity generation. In order to leverage shallow hot dry rock (HDR) fields, the present paper proposes an alternative to enhanced geothermal systems (EGS): thermoelectric generators. Based on the conditions of Timanfaya National Park, a prototype has been built to experimentally analyze the feasibility of the proposed solution. The prototype is composed by a two phase closed thermosyphon (TPCT) as hot side heat exchanger, two thermoelectric modules, and it considers different cold side heat exchangers: fin dissipators assisted by a fan and loop thermosyphons, both with various geometries. Experiments have demonstrated that loop thermosyphons represent the best alternative due to their low thermal resistance and, especially, due to their lack of auxiliary consumption, leading to a maximum net power generation of 3.29 W per module with a temperature difference of 180 °C (200 °C in the hot side and 20 °C as ambient temperature), 54% more than with fin dissipators. Hence, there exists a new opportunity for electricity generation in shallow hot dry rock fields: thermoelectric generators with biphasic thermosyphons as heat exchangers, a patented and robust solution.

description Publicationkeyboard_double_arrow_right Article 2016 SpainPublisher:Asociación Española de Historia Económica (AEHE) Authors: Rubio Varas, María del Mar; Torre Campo, Joseba de la;Rubio Varas, María del Mar; Torre Campo, Joseba de la;En 1972, Henry Kearns, presidente y director del Export-Import Bank de los Estados Unidos (Eximbank), visitó la Cámara Oficial de Comercio e Industria de Madrid. El título de su discurso'España – el cliente del billón de dólares del Eximbank' daba cuenta del importante papel que el banco público estadounidense jugaba en la financiación de las compras españolas de bienes de equipo, como aviones, fábricas de acero, estaciones satelitales y plantas eléctricas, entre otros. La concentración en nuevas instalaciones de generación eléctrica convertía a España en aquel momento en el país con el más rápido desarrollo de energía nuclear de Europa, y el mayor comprador de tecnología nuclear de los EE.UU. mano a mano con Japón. Ninguna otra nación se acercó a estos dos en ese sentido. Utilizando materiales de archivo del Eximbank y la Administración Nacional de Archivos y Registro de los Estados Unidos (NARA), exploramos las facilidades financieras que los EE.UU. proporcionaron al programa nuclear español, el tamaño de los créditos autorizados y su evolución en el tiempo. Se hace evidente que el bombeo de dinero público norteamericano para la exportación de las instalaciones nucleares en el mundo explica en gran medida el cuasimonopolio del mercado nuclear mundial que los EE.UU. tuvieron antes de la década de 1980, y en particular su importancia para convertir a España en uno de los pioneros y líder en la adopción de la tecnología nuclear. In 1972, Henry Kearns, President and Chairman, Export-Import Bank of the United States (Eximbank) visited the Official Chamber of Commerce and Industry in Madrid. The title of his speech 'Spain—Eximbank’s Billion Dollar Client' gave notice of the important role that the public American bank had for financing the Spanish purchases of capital equipment: aircrafts, steel mills, satellite grown stations, power plants, etc. The heavy concentration on new power facilities at the time made Spain the fastest growing nuclear power developer in Europe, and the largest nuclear power buyer from the US with Eximbank’s support head-to-head with Japan. No other nation approached these two in that respect. Investigating archival materials from the Eximbank and the National Archives and Record Administration of the United States (NARA), we explore the financial facilities the US provided to the Spanish nuclear program, the size of the authorised credits and its evolution over time. It became apparent that the role of the US in pumping public money for exporting nuclear facilities to the world explain a great deal of the US quasi-monopoly of global nuclear market before the 1980s, and in particular for turning Spain into an early adopter and champion adopter of nuclear technology. Financial support from the Bank of Spain (grant agreement 30/6/2012) and the Spanish Ministry of Economics and Competitiveness (project ref.: HAR2014-53825-R) is dully acknowledged.

Spain was the first developing country to exploit a nuclear power plant commercially. By the early 1970s Spain had become the major nuclear client of the USA, the world’s largest reactor exporter. Despite its importance, historians are just beginning to revisit and establish the sequence of the events that make up Spain’s nuclear history. This article analyses the role played by the state in enabling one of Western Europe’s poorest countries to join the exclusive nuclear power club. In a departure from the technological approach used in previous literature, the history of Spain’s progress in the nuclear power field is retraced against the background of its political and economic evolution.

Se trata de un ejemplo de industria naciente que, bajo la protección del Estado y la acción de los consorcios empresariales y de las multinacionales norteamericanas, fue capaz de replicar un reto tecnológico complejo. Analizamos cómo se fue creando un ecosistema empresarial en el que fue clave el liderazgo de algunos ingenieros y la cooperación y competencia entre industrias, ingenierías y consultoras. La historia empresarial de las centrales nucleares de Zorita y Garoña ejemplifica un modelo de learning by doing que, a través de los contratos 'llave en mano', permitieron un rápido crecimiento del sector, convenciendo al gobierno de la dictadura y a los promotores eléctricos de que era posible llevar a cabo uno de los programas nucleares más ambiciosos de la Europa occidental. This article explores the learning and technology transfer processes that placed Spain among the firstcomers of nuclear energy in the late 1960s. It is an example of a infantindustry that, under the protection of the State and the action of the business consortiums and of the North American multinationals, was able to replicate a complex technological challenge. We analyzed how an entrepreneurial ecosystem was created in which the leadership of some engineers and the cooperation and competition between industries, engineering and consultants were key. The business history of the Zorita and Garoña nuclear power plants exemplifies a model of learning by doing that, through turnkey contracts, allowed a rapid growth of the sector, convincing the dictatorship government and the electric promoters that it was possible to carry out one of the most ambitious nuclear programs in Western Europe.

Power-to-methane (PtM) systems may allow fluctuations in the renewable energy supply to be smoothed out by storing surplus energy in the form of methane. These systems work by combining the hydrogen produced by electrolysis with carbon dioxide from different sources to produce methane via the Sabatier reaction. The present work studies PtM systems based on the CO supplied by the chemical looping combustion (CLC) of biomass (PtM-bioCLC). Life- cycle- assessment (LCA) was performed on PtM-bioCLC systems to evaluate their environmental impact with respect to a specific reference case. The proposed configurations have the potential to reduce the value of the global warming potential (GWP) climate change indicator to the lowest values reported in the literature to date. Moreover, the possibility of effectively removing CO from the atmosphere through the concept of CO negative emissions was also assessed. In addition to GWP, as many as 16 LCA indicators were also evaluated and their values for the studied PtM-bioCLC systems were found to be similar to those of the reference case considered or even significantly lower in such categories as resource use-depletion, ozone depletion, human health, acidification potential and eutrophication. The results obtained highlight the potential of these newly proposed PtM schemes.

Previous papers on this topic fall short as comparing finite-element models with simplified versions of resistance–capacitance models. It was confirmed that resistance–capacitance models replicate results of finite-element models in the simulation of a thermoelectric module under steady-state conditions. Deviations lower than 3 % in electric power and efficiency (ratio of electric power to heat input) are obtained for temperature differences between heat source and heat sink as large as 200 K. Similarly, deviations lower than 3 % are obtained for simulation of a thermoelectric module under transientstate conditions. Resistance-capacitance models not only replicate values, trends and rates of variation predicted by finite-element models under step, linear and sinewave variations in the boundary conditions, but they also do this with negligible computational cost.

An important issue in thermoelectric generators is the thermal design of the heat exchangers since it can improve their performance by increasing the heat absorbed or dissipated by the thermoelectric modules. Due to its several advantages, compared to conventional dissipation systems, a thermosyphon heat exchanger with phase change is proposed to be placed on the cold side of thermoelectric generators. Some of these advantages are: high heat-transfer rates; absence of moving parts and lack of auxiliary con- sumption (because fans or pumps are not required); and the fact that these systems are wickless. A com- putational model is developed to design and predict the behaviour of this heat exchangers. Furthermore, a prototype has been built and tested in order to demonstrate its performance and validate the compu- tational model. The model predicts the thermal resistance of the heat exchanger with a relative error in the interval [?8.09;7.83] in the 95% of the cases. Finally, the use of thermosyphons with phase change in thermoelectric generators has been studied in a waste-heat recovery application, stating that including them on the cold side of the generators improves the net thermoelectric production by 36% compared to that obtained with finned dissipators under forced convection. The authors are indebted to the Ministry of Economy, Industry and Competitiveness-Government of Spain and FEDER Funds for economic support of this work, included in the DPI2014-53158-R Research Project.

Waste heat generation has a widespread presence into daily applications, however, due to the low-temperature grade which presents, its exploitation with the most common technologies is complicated. Thermoelectricity presents the possibility of harvesting any temperature grade heat; besides it also includes many other advantages which make thermoelectric generators perfect for generating electric power from waste heat. A prototype divided into two levels along the chimney which uses the waste heat of a combustion has been built. The experimentation has been used to determine the parameters that influence the generation and to validate a generic computational model able to predict the thermoelectric generation of any application, but specially applications where waste heat is harvested. The temperature and mass flow of the flue gases and the load resistance determine the generation, and consequently, these parameters have been included into the model, among many others. This computational model incorporates all the elements included into the generators (heat exchangers, ceramics, unions) and all the thermoelectric phenomena and moreover, it takes into account the temperature loss of the flue gases while circulating along the thermoelectric generator. The built prototype presents a 65 % reduction in the generation of the two levels of the thermoelectric generator due to the temperature loss of the flue gases. The general computational model predicts the thermoelectric generation with an accuracy of the ±12 %. The authors are indebted to the Spanish Ministry of Economy and Competitiveness for the economic support to this work, included in the DPI2014-53158-R research project.

Nuclear energy was one among business opportunities brought by the take off in science and technology after the Second World War. The narratives of the milestones of atomic history neglect the commercial, industrial and organizational aspects that made it possible. This paper concentrates on what makes the nuclear business exceptional (or not). We undertake an analysis of the nuclear supply business (designing, manufacturing and installing nuclear facilities) distinct from the analysis of the demand side (business operating nuclear power plants). We identify a continuing role of the state in civil nuclear businesses and a symbiotic relationship with private atomic business. And yet, for the most part the nuclear business applies the usual criteria of cost minimization and profit maximization within the boundaries of a non-perfectly competitive market. We argue that the development of civil nuclear projects is core not just to business history as a discipline but to post-war history. © 2021 The Author(s).

Aranguren; Miguel Araiz; Gurutze Perez; David Astrain;Despite being one of the largest renewable sources, geothermal energy is not widely utilized for electricity generation. In order to leverage shallow hot dry rock (HDR) fields, the present paper proposes an alternative to enhanced geothermal systems (EGS): thermoelectric generators. Based on the conditions of Timanfaya National Park, a prototype has been built to experimentally analyze the feasibility of the proposed solution. The prototype is composed by a two phase closed thermosyphon (TPCT) as hot side heat exchanger, two thermoelectric modules, and it considers different cold side heat exchangers: fin dissipators assisted by a fan and loop thermosyphons, both with various geometries. Experiments have demonstrated that loop thermosyphons represent the best alternative due to their low thermal resistance and, especially, due to their lack of auxiliary consumption, leading to a maximum net power generation of 3.29 W per module with a temperature difference of 180 °C (200 °C in the hot side and 20 °C as ambient temperature), 54% more than with fin dissipators. Hence, there exists a new opportunity for electricity generation in shallow hot dry rock fields: thermoelectric generators with biphasic thermosyphons as heat exchangers, a patented and robust solution.
